Content
7%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This skill reads as a role description or persona prompt rather than an actionable skill. It exhaustively catalogs security topics Claude already knows well, without providing any concrete code examples, specific implementation patterns, or executable guidance. The content would be far more effective if it were reduced to ~20% of its current size and replaced the taxonomic lists with specific, copy-paste-ready code patterns for the most critical security implementations.
Suggestions
Replace the abstract capability lists with concrete, executable code examples for the most critical patterns (e.g., parameterized queries, JWT validation, CSP header configuration, input validation middleware).
Remove the 'Knowledge Base', 'Behavioral Traits', and 'Capabilities' taxonomy sections entirely — Claude already knows these concepts. Focus only on project-specific conventions or non-obvious implementation details.
Add explicit validation/verification workflows, e.g., 'After implementing auth, verify by: 1. Run `npm test -- --grep security` 2. Check that invalid tokens return 401 3. Verify refresh token rotation invalidates old tokens'.
Move detailed reference material into the referenced 'resources/implementation-playbook.md' and keep SKILL.md as a concise overview with quick-start patterns and clear pointers to detailed docs.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Extremely verbose and padded with information Claude already knows. The bulk of the content is a taxonomy of security concepts (OWASP Top 10, JWT, CSRF, etc.) that Claude is already deeply familiar with. Lists like 'Behavioral Traits', 'Knowledge Base', and 'Capabilities' describe general security knowledge rather than providing new, actionable instructions. The 'Example Interactions' section lists prompts rather than providing useful examples. | 1 / 3 |
Actionability | No concrete code, commands, or executable examples anywhere in the skill. The entire content is abstract descriptions and categorized lists of security topics. Statements like 'Implement input validation with comprehensive sanitization and allowlist approaches' are vague directions, not actionable guidance. There are zero code snippets, zero specific implementation patterns, and zero copy-paste-ready solutions. | 1 / 3 |
Workflow Clarity | The 'Response Approach' section lists 9 high-level steps but they are abstract and lack any validation checkpoints, error recovery, or concrete sequencing. For a skill dealing with security implementations (which are inherently risky operations), there are no verification steps, no testing workflows, and no feedback loops. | 1 / 3 |
Progressive Disclosure | There is one reference to an external file ('resources/implementation-playbook.md') which suggests some progressive disclosure intent. However, the main content is a monolithic wall of categorized lists that could be dramatically shortened or split into separate reference files. The structure uses headers but the content under each is just bullet-point descriptions rather than actionable overviews. | 2 / 3 |
